Cats do not answer to names. A tisking noise suffices. I give the name Kitty to the vets, but it allows for you to rename the cat a lot. For examples, when our last cat was very young, she could jump way more than most cats. This equaled out though, as she had about my sense of balance. So she would jump from the desk to the top of the door and promptly fall off. Jump to the top of the refrigerator, get alarmed by the bread basket that was in the same location every time and fall off sliding down the side of the refrigerator, claws flailing in every direction. Her name during that period was "Grace".
Later, she calmed down in the jumping, but it seems we made a mistake by talking to the cat. We would be drunk and make "cat noises" at her and she would reply. It seemed cute at the time, however she became more and more vocal after this. If she wanted food (even if there was food in the bowl) she would meow at you constantly. I remember telling a cocktail at the casino I worked at, "Yeah, we named the cat after you." She replied, "awwww how sweet." I said, "Yeah, Melanie seemed appropriate as she is really cute, but bitches all the time."
Her current name is Fido as she is fat and tolerates you petting her like a dog.
